Hollow Knight MultiWorld vs Universal Pokémon Randomizer FVX

Hollow Knight MultiWorld is a free, open-source set of add-ons for Hollow Knight Randomizer 4.0. MultiWorld distributes randomized items across linked game files for cooperative play, while the separate ItemSync add-on shares randomized pickups among players in a room. Players can use local randomizer mods, keep their own randomizer settings, choose nicknames shown when their items are collected elsewhere, and coordinate through a room code. The server assigns a random identifier to each randomization, allowing multiple sessions to run at once. Players can save, reload, reconnect, and rejoin to recover MultiWorld data after a crash before their first save. Mods are available through Scarab, which installs dependencies. Documentation lists a public server and explains local hosting with MultiWorldServer.exe; WAN access requires forwarding port 38281. The project supports Windows, offers advanced customization, seed sharing, and multiworld support, and is licensed under LGPL-2.1. Detailed spoiler logs are planned.

Universal Pokémon Randomizer FVX is a free, open-source desktop tool for changing data in vanilla core-series Pokémon games from Generations 1–7. It supports games for Game Boy, Game Boy Color, Game Boy Advance, Nintendo DS, and Nintendo 3DS, with Pokémon: Let’s Go, Pikachu! and Let’s Go, Eevee! excluded. Options cover Pokémon traits, evolutions, starters, moves, trainer and wild Pokémon, items, and type effectiveness. FVX adds palette randomization and custom player graphics, with support varying by generation: palettes are fully supported in Generations 1–3, partly supported in 4–5, and unavailable in 6–7; custom player graphics are limited to Generations 1–3. A seed and settings string can reproduce a randomization, and logs can be disabled to prevent spoilers during races. Users must provide their own ROM files. ROM hacks are not officially supported. For 3DS games, files must be decrypted; randomized output can be saved as CXI or LayeredFS. If a game update is loaded, LayeredFS is the only output option. The tool runs on Linux, macOS, and Windows.
